MAP 5050: Power 2145-CG8 and 2145-CF8

This topic helps you to solve power problems that have occurred on SAN Volume Controller models 2145-CG8 and 2145-CF8.

1. Are you here because the node is not powered on?

   NO

   Go to step 11.

   YES

   Go to step 2.

2. (from step 1)

   Is the power LED on the operator-information panel continuously illuminated? Figure 1 shows the location of the power LED  1  on the operator-information panel.

   Figure 1. Power LED on the SAN Volume Controller models 2145-CG8 or2145-CF8 operator-information panel

   

   NO

   Go to step 3.

   YES

   The node is powered on correctly. Reassess the symptoms and return to MAP 5000: Start or go to MAP 5700: Repair verification to verify the correct operation.

3. (from step 2)

   Is the power LED on the operator-information panel flashing approximately four times per second?

   NO

   Go to step 4.

   YES

   The node is turned off and is not ready to be turned on. Wait until the power LED flashes at a rate of approximately once per second, then go to step 5.

   If this behavior persists for more than three minutes, perform the following procedure:

   1. Remove all input power from the SAN Volume Controller node by removing the power retention brackets and the power cords from the back of the node. See "Removing the cable-retention brackets" to see how to remove the cable-rentention brackets when removing the power cords from the node.
   2. Wait one minute and then verify that all power LEDs on the node are extinguished.
   3. Reinsert the power cords and power retention brackets.
   4. Wait for the flashing rate of the power LED to slow down to one flash per second. Go to step 5.
   5. If the power LED keeps flashing at a rate of four flashes per second for a second time, replace the parts in the following sequence:
      • System board

   Verify the repair by continuing with MAP 5700: Repair verification.

4. (from step 3)

   Is the Power LED on the operator-information panel flashing approximately once per second?

   YES

   The node is in standby mode. Input power is present. Go to step 5.

   NO

   Go to step 6.

5. (from step 3 and step 4)

   Press the power-on button on the operator-information panel of the node.

   Is the Power LED on the operator-information panel illuminated a solid green?

   NO

   Verify that the operator-information panel cable is correctly seated at both ends.

   If you are working on a SAN Volume Controller 2145-CG8 or 2145-CF8, and the node still fails to power on, replace parts in the following sequence:

   1. Operator-information panel assembly
   2. System board

   Verify the repair by continuing with MAP 5700: Repair verification.

   YES

   The power-on indicator on the operator-information panel shows that the node has successfully powered on. Continue with MAP 5700: Repair verification to verify the correct operation.

6. (from step 4)

   Is the rear panel power LED on or flashing? Figure 2 shows the location of the power LED  1  on the 2145-CF8 or the 2145-CG8.

   Figure 2. Power LED indicator on the rear panel of the SAN Volume Controller 2145-CG8 or 2145-CF8

   

   NO

   Go to step 7.

   YES

   The operator-information panel is failing.

   Verify that the operator-information panel cable is seated on the system board.

   If you are working on a SAN Volume Controller 2145-CG8 or 2145-CF8, and the node still fails to power on, replace parts in the following sequence:

   1. Operator-information panel assembly
   2. System board

7. (from step 6)

   Locate the 2145 UPS-1U (2145 UPS-1U) that is connected to this node.

   Does the 2145 UPS-1U that is powering this node have its power on and is its load segment 2 indicator a solid green?

   NO

   Go to MAP 5150: 2145 UPS-1U.

   YES

   Go to step 8.

8. (from step 7)

   Are the ac LED indicators on the rear of the power supply assemblies illuminated? Figure 3 shows the location of the ac LED  1  and the dc LED  2  on the rear of the power supply assembly that is on the rear panel of the 2145-CF8 or the 2145-CG8.

   Figure 3. Power LED indicator and ac and dc indicators on the rear panel of the SAN Volume Controller 2145-CG8 or 2145-CF8

   

   NO

   Verify that the input power cable or cables are securely connected at both ends and show no sign of damage; otherwise, if the cable or cables are faulty or damaged, replace them. If the node still fails to power on, replace the specified parts based on the SAN Volume Controller model type.

   Replace the SAN Volume Controller 2145-CG8 or 2145-CF8 parts in the following sequence:

   1. Power supply 675W

   YES

   Go to step 9 for SAN Volume Controller 2145-CG8 or 2145-CF8 models.

   Go to step 10 for all other models.

9. (from step 8)

   Is the power supply error LED on the rear of the SAN Volume Controller 2145-CG8 or 2145-CF8 power supply assemblies illuminated? Figure 2 shows the location of the power LED  1  on the 2145-CF8 or the 2145-CG8.

   YES

   Replace the power supply unit.

   NO

   Go to step 10

10. (from step 8 or step 9)

    Are the dc LED indicators on the rear of the power supply assemblies illuminated?

    NO

    Replace the SAN Volume Controller 2145-CG8 or 2145-CF8 parts in the following sequence:

    1. Power supply 675W
    2. System board

    YES

    Verify that the operator-information panel cable is correctly seated at both ends. If the node still fails to power on, replace parts in the following sequence:

    1. Operator-information panel
    2. Cable, signal, front panel
    3. System board (if the node is a SAN Volume Controller 2145-CG8or SAN Volume Controller 2145-CF8)

    Verify the repair by continuing with MAP 5700: Repair verification.

11. (from step 1)

    The node will not power off immediately when the power button is pressed. When the node is fully booted, power-off is performed under the control of the SAN Volume Controller software. The power-off operation can take up to five minutes to complete.

    Is Powering Off displayed on the front panel?

    NO

    Go to step 12.

    YES

    Wait for the node to power off. If the node fails to power off after 5 minutes, go to step 12.

12. (from step 11)
    Attention: Turning off the node by any means other than using the management GUI might cause a loss of data in the node cache. If you are performing concurrent maintenance, this node must be deleted from the system before you proceed. Ask the customer to delete the node from the system now. If they are unable to delete the node, call your support center for assistance before you proceed.
    The node cannot be turned off either because of a software fault or a hardware failure. Press and hold the power button. The node should turn off within five seconds.

    Did the node turn off?

    NO

    Turn off the 2145 UPS-1U that is connected to this node.

    Attention: Be sure that you are turning off the correct 2145 UPS-1U. If necessary, trace the cables back to the 2145 UPS-1U assembly. Turning off the wrong 2145 UPS-1U might cause customer data loss.

    Go to step 13.

    YES

    Go to step 13.

13. (from step 12)

    If necessary, turn on the 2145 UPS-1U that is connected to this node and then press the power button to turn the node on.

    Did the node turn on and boot correctly?

    NO

    Go to MAP 5000: Start to resolve the problem.

    YES

    Go to step 14.

14. (from step 13)

    The node has probably suffered a software failure. Dump data might have been captured that will help resolve the problem. Call your support center for assistance.
